This invention materially enhances the quality of the environment and mankind by contributing to the restoration or maintenance of the basic life-sustaining natural elements, by reducing the amount of carbon monoxide introduced to the atmosphere from a combustion system, achieved by furnishing a system's approach to optimize the amount of oxygen to be chemically combined with fuel upon ignition of both allowing the correct amount of carbon to combine with the correct amount of oxygen thus fully release the thermal energy stored therein.

A burner includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.

The present invention discloses a cold gas spraying gun with a powder injector for injecting a gas/powder mixture into a mixing chamber through which a process gas flows. One powder injector pipe of the powder injector is closed at one face end. A delivery opening for delivering the gas/powder mixture from the powder injector is designed as an opening in a side wall of the powder injector pipe. The delivery opening opens into the hollow chamber in the powder injector pipe at an axial distance from the closed face end of the powder injector pipe, and therefore a backed-up volume is located between the delivery opening and the closed end face of the powder injector pipe.

The invention relates to a burner, particularly for the gasification of solid carbonaceous materials by partial combustion. The burner comprises a central channel (2) and at least one coaxial channel (6). The channels (2, 6) are defined by concentric walls (3, 5) having free downstream outer ends profiled to define an annular slit (10) forming a discharge end of the coaxial channel (6) and converging towards an adjacent discharge end of the central channel (2). The burner (1) is encased by a cooling jacket (14) and comprises a front face (21) with double walls spaced by one or more baffles (28) defining a coolant flow path operatively connected to the cooling jacket (14). The cooling jacket (14) has an upstream section (14A) and a transitional section (25) narrowing down to the front face (21) having a smaller outer diameter than the upstream cooling jacket section.

An apparatus is provided for a turbine engine. This turbine engine apparatus includes a fuel injector nozzle extending axially along an axis to a nozzle tip. The fuel injector nozzle includes an inner fuel passage and an outer fuel passage. The inner fuel passage extends axially within the fuel injector nozzle to an inner passage outlet at the nozzle tip. The inner passage outlet is formed by an inner divergent surface. The inner divergent surface is angularly offset from the axis by a first acute angle. The outer fuel passage extends axially within the fuel injector nozzle to an annular outer passage outlet at the nozzle tip. The annular outer passage outlet is formed by an outer divergent surface. The outer divergent surface is angularly offset from the axis by a second acute angle that is greater than the first acute angle.

An apparatus is provided for a turbine engine. This turbine engine apparatus includes a monolithic body. The monolithic body includes a splash plate and a fuel nozzle. The splash plate includes a splash plate surface. The fuel nozzle includes a nozzle orifice. The fuel nozzle is configured to direct fuel out of the nozzle orifice to impinge against the splash plate surface.

A combustor system for an aerial vehicle can include an outer case with a first and second end, an inner combustor case with a lumen, a central combustor chamber, an air flow path between the outer case and inner combustor case, an integrated air scoop attached to the inner combustor case at the lumen that directs air from the air flow path into the central combustor chamber, a wedge within the integrated air scoop, a second integrated air scoop attached to the outer case, a bifurcated orifice integrated into the second integrated air scoop, a fuel manifold and fuel orifice within the first integrated air scoop, and a splash plate with a first and second face, the splash plate extending through the lumen into the central combustor chamber. The first and second integrated scoops can interlock and seal by pushing the wedge into the bifurcated orifice.

An aircraft engine combustor equipped with a cylindrical member for demarcating an internal space which extends along an axis, and a fuel nozzle which is positioned in a manner such that at least a part thereof is positioned inside the internal space, and has an injection hole through which a liquid fuel is injected toward the inner-circumferential surface of the cylindrical member, wherein the cylindrical member is configured in a manner such that the entirety, in the circumferential direction, of a tip end surface extending radially outward from the discharge port end of the inner-circumferential surface has a first contact angle relative to the liquid fuel which is less than 90.

A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.
